我试着在class="content“id="testtimonals”一节中使用"bg- faded“作为褪色的背景,但它在页面上没有显示任何效果。

During the summer, our rabbit, Tonto, began to have severe redness and itching on his belly and feet. I'm very thankful to the veterinarians and staff at Wisdom for the excellent care Tonto received, and for nipping his allergies in the bud, so to speak.

简短回答:
将.bg-faded替换为.bg-light,您的代码将正常工作,如this fiddle中所示。
详细答案:
.bg-faded来自过时的alpha version of Bootstrap

因为我不认为您使用的是Bootstrap的alpha版本,所以我建议您参考current v4.5 docs,其中.bg-faded被.bg-light取代
